Change Menu for Sydney Theme

Hi,

I’m having problems changing the menu fonts for my website. I am using the Sydney theme (https://ww.wp.xz.cn/themes/sydney/).

I am fairly new to wordpress and have tried (and failed) to figure out what the exact css selectors are that I need to change to make this happen.

Any help you could give me would be much appreciated. Btw my website is botmechanics.com if that helps.

Cheers.
